Exsemjingo, best that you build some thick skin now. The answer to the question you were asking was given several times in the thread by a number of members, yet you kept asking the question. Folks have two options then; consider that you are either not getting it and try to explain it differently, or consider that you are being somewhat obstinate about not receiving an answer which lines up exactly with what you are expecting. Nobody was trying to be a prick there. I can tell you, I was following this thread for a bit, saw that the answer about the "Column C DEO 2LT" had been answered and was thinking about which point you might need a "written 2x4 across the forehead" to help the info sink in. I think George was actually being rather kind to you.
The "takeaway" from this for you should not be the answer that a DEO candidate is an OCdt until you pass of the parade square at graduation in St.Jean, thus becoming a "Column C" DEO 2Lt, but rather learning the lesson of making best use of the tools available to you to accomplish something, in this case finding the relatively simple and "out there for all to see" answer to a question. Nobody is asking you to prostrate yourself to some superior being to get the answer, but a bit less obstinacy/more humility might be something to think about.
Life in the military has its challenges. It is also a very social organisation so your personal interaction skills, be they as used with peers, to superiors or, in due course, to any subordinates you may have are the foundation of how you would live out your life in the military.
Food for thought.
Cheers,
